To all whom it may concern: 7

Be it known that I, ALBERT WV. ERIoKsoN,

a citizen of the United States, and residing in New York city, in the county and State of New York, have invented certain new and useful Improvements in Printing Rules, of-which the following'is a clear and exact description, referencebeing hadto the accompanying drawings, formingpart of this specification. I

This invention relates to printing 7 and particularly to tabular and catalogwork.-

The invention has for an object to save labor, to increase speed and to provide a sure mcans of producing flawless work.

The invention has fora further object tov eliminate abstruse calculations having to do with the placing: of dividing rules. 7

The invention has for a further object to provide a structure such thatwhen the table is dead, the rules can extracted as quickly or even more quickly than a lead can be pulled and laid for another job. i This invention has for a further object'to provide brass rules that are light and inex pensive and that can be'cut to any measure and punched for the printing device as easily as could the old leads.

The invention has for a further object the provision of rules which are reversible so that they can be turned to print a thin lineor a thick line or parallel lines as desired.

The invention has for a further object a structure such that a very thin line may be printed at the edge of the work so that the printing of a title, heading or other notation may be brought close to the tabular composition. V I

Other objects willjappear as the description proceeds.

Reference is made to the drawings for. a detailed description of a preferred embodi ment ofthe invention which is to be taken in connection with the specification as a, part thereof in which I Figure 1 is a perspective view with the parts broken away from one another to show how the rules are placed in position.

It is by a simpleoperation in arithmetic, namely, the thickness of the title heading slug, 6 points, plus the thickness of each of the type metal rules, 2 points, makes a total of 10 points. But the slugs 7 are each 6 points thick and therefore in displacing them a thickness that is a multiple of six points must beprovided for. In this case opposite the subheading slug 10 there are 2 105 transverse printing slugs 8 of shorter length t e g oov s 3 slugs 2 and 1.

than slugs 7. In order to make an even and uniform thickness a 21 point leading slug is inserted between the printing rule slug 12 andthe approximate transverse printing slu 7.

referring to Figure 10 there is shown one of my improved reversible printing rules 17. This reversible printing rule may have difierent orthe same printing surfaces 19 on top, and 20 on the bottom, so that it maybe I reversed to print a thickline or a thin line or to print some kindof line with either edge. At both ends of the rules 17 there is provided a rectangular extension 18 which is adapted to be insertedin the grooves 3 and 1 of the end These rules are cut to the desired length by means of a special tool of my own invention and therefore the rules can be easily prepared. The full length rules 17 fit in grooves 16 which are cut by a special machine invented by me to such a depth that when one edge of each rule rests on the bottom of the corresponding groove the opposite edge of said rule lies in the plane of the printing face. When a subheadin 10 is inserted in the tabular composition t e rules are not passed the entire e. length of the formand are cut to lengths sojlthat they terminate at the subheading slug. rules 21 and 22 are held by means of. lugs 181at one end in, the roovesBand 4 of the end slugs '1 and 2. in cutting the rectangular extension or lug 18 on the oppo- 7 site ends of these brass rules, .21 'and 22, in

the case of rules 21 which are held in the apertures 14 in the type metalrule 11, they are cut to a length of 2 points so that they do not protrude lrom the opposite side of the rule 11; but inthc case of the rules 22 where the extensions 18 must pass over the spaeesmade by the leading slugs 13, the extensions 18 which lie near the subheading 10 are cut by my special tool to a length of 4' points. 7

It is apparent that I have invented an improved device for use in tabular composition whereby the rules may bequickly made and quickly and"accurately fixed in position in the printing form; They are securely locked whether they extend the entire length of the form or a part length. They are tion,,;- type slugs with grooves provided L transversely of theirprinting portions, a reversible printing {rule to fit within the grooves, the rule havingreduced' ends, centrallyklisposed. relatively to its height, and opposite end slugs having longitudinally continuous recesses adapted to engage the 7 reduced ends of the rule.
